Woodworkbykirk is right. I would go with the 11.25'' treads if you have the horizontal space, and a landing would be ideal. Australian code requires a maximum of 18 straight risers before you need a landing at least 4' in length, but I consider this extreme if you have room for an intermediate landing.
Allow 8'' on the top landing and 14'' at the bottom for this. This measurement will determine how long the stair lift rail needs to be. Measure from the landing edge of the top stair to the floor at the bottom, in a diagonal line. Measure this at several points along the staircase, as it might vary slightly.
